PNG kuya SVG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-PNG ibe yi-SVG ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho PNG futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-SVG. Kuzo zonke izimo ezingenalutho (PNG, TIFF, BMP) wonke ama-pixel agcinwa nge-bit-by-bit; kuzo zonke izimo ezingenalutho (JPG, WebP) ungalungisa i-quality factor (iphutha 90) ngaphambi kokufaka ngezansi. I-PNG isebenzisa ukucindezeleka kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele. I-SVG igcina amafomu njengendlela ye-matematics nesihloko njengesihloko, hhayi njenge-pixels, ngakho-ke iyidokhumende kunaleyo ye-raster grid.

Ingabe isithombe PNG singaguqulwa ibe yi SVG ehlanzekile?

Kuze kube yilapho, futhi kufanelekile ukuhlela okulindelekile kuqala. Ukulandelela kushintsha ama-pixels ama-regions abe izimo, okusebenza kahle kumalogo, umdwebo welayini kanye nama-graphic amnyama-nombala ocacile nama-borders acacile. Isithombe asikho isithombe esinjalo, ngakho-ke ukulandelela kuletha noma i-posterized approximation eqinile noma i-SVG enezigidi zama-paths ezikhulu futhi ezihamba kancane ukuveza kune-original. I-SVG ayikwazi ukukhombisa isithombe - ukulandelela okuthile kwenza noma ukulinganiselwa okuncane noma ifayela elikhulu kunalo raster yakuqala.

Ubhalo ngaphakathi kwe-SVG usebenza kanjani?

Ku-SVG, umbhalo ubhalwe ngokusemthethweni - ukhethwa, utholakale futhi uphinde ushintshwe, futhi kudinga ukuthi umbhalo ubekhona noma ufakwe ukuze usebenze ngendlela efanele. Ukushintsha kusuka ku-SVG kushintsha umbhalo ube yi-pixels noma ube umbhalo wedokhumende ngokuya ngenjongo; ukuguqula ku-SVG kwenza kuphela umbhalo osemthethweni uma umsuka une-text layer ukuqala.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe PNG ne SVG?

Akukho data ye-pixel, cha. Ifomethi zombili zigcina isithombe ngaphandle kokucindezeleka okulahlekile, ngakho isithombe esiphumayo sifana nesinye esingene ngaphakathi futhi ukuguqulwa kungaphinda kwenziwe ngaphandle kweso. Okunye okushintshayo yisayizi yefayela, futhi okunye okuphawulekayo ukushayela — ububanzi bombala, amaprofayili afakwe, ama-layers kanye nobuciko bonke baxhaswa ngokuhlukile phakathi kwefomethi engalahleki.

Ingabe ukuguqulwa PNG kuya ku SVG kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho SVG i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ibe yi-JPG kuzoba ne-alpha channel efana nendawo yangasemva ebomvu — uma ufuna ukubukeka okucacile, khetha okuzokwazi ukubukeka okucacile endaweni ye-SVG. I-SVG iyifomethi ye-W3C XML-based vector, isinqumo kusukela ngo-2001 futhi manje ikhona kunoma iyiphi i-browser.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala i PNG kuya ku SVG?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka kumthombo PNG futhi axhunywe kabusha ku-SVG lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi enza i-profayili ayixhasi ibuyela emuva ku-sRGB nge-soft-proof step.

Yini ekwenzeke ku-EXIF metadata uma uguqula PNG usuka ku-SVG?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi PNG -> SVG lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukushintsha ubumfihlo ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokutholakala kwendawo noma idivayisi-fingerprint.

Ingabe ngingenza ukuguqulwa kwekhulu le PNG amafayela ku SVG ngasikhathi sinye?

Yebo — cindezela amafayela amaningi PNG endaweni yokulayisha futhi babeke ifile ngokufanayo. Isigaba esimahhala sithatha ama-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza ngemisebenzi eminingi efana, ngakho-ke isithombe esingu-200 siqedela ngezansi kwemizuzu emibini.

Ingabe PNG kuya ku SVG iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi elula sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor esebenzisa, ngekhwalithi efanayo. Ushintsho ukuthi amathuluzi wedesktop avula ifayela elinye ngasikhathi sinye; sivumela iqembu futhi sisebenzisana nabo kubasebenzi bekhasimende.

Yini isixazululo kanye nezici zehele SVG?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-SVG yakho yesokudla inezici ze-pixel ezifanayo ne-PNG. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva, noma ubeke izinhlelo nge- /image-pipeline/ utility.

Ingabe ihele SVG lincane uma kungabonakali izinto ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuletha i-SVG 60-80% encane kune-PNG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless SVG (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono kune-source esenayo. I-SVG ibonisa kahle nganoma yisiphi isibalo, ihlala ihleliwe, itholakale futhi ihlukaniswe njengetekisi elijwayelekile, futhi ivame ukuba yingxenye yesimo se-PNG.

Ingabe amafayela ami PNG afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu PNG aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina, noma ukuhlanganisa idatha ye-pixel. Ifasitela eligcwele lokugcinwa libhalwe ku /privacy/.

PNG

Amafayela we-PNG asebenza ngokucacile futhi asebenzisa ukucindezeleka okungalahleki, okwenza kube ngcono kakhulu kuma-graphic, amalogo, nama-screenshots.
